Huddle stated that she extended it because of her 14.51 in Paris. However, and the insinuation is well sourced here, she confirmed through interview(s) between July 19 and July 22 that she was defending Bix. July 23 she drops; morning of Bix they announce drug tests. Really, when she confirms multiple times only the day before she drops?
As an athletics reporter covering various stories, I can tell you that nothing is more newsworthy than information surrounding PEDs. Huddle isn't receiving allegations, but her decision has raised suspicion. Any reporter worth salt is following suspicions. That is the job.
I see that she is start-listed for Ninove.. It answers the OP.
So that you understand, I will undoubtedly continue to "baffle you". And I'll have a story ready to go should something more than suspicion arise.
